Exploring Ad Formats on LinkedIn: A Comprehensive Look
LinkedIn offers various ad formats to tailor fit your marketing goals and strategies. Understanding these formats is key to creating a successful LinkedIn Ads campaign.
LinkedIn Sponsored Content: Engage with Precision
Sponsored content from LinkedIn appears directly in users' feeds, much like ordinary posts. However, these posts are marked as promoted. The feed placement results in numerous impressions and clicks. Sponsored content can include single image ads, carousel ads with multiple images, or video ads.
You can lead your audience to a landing page or a blog post, or directly advertise a lead magnet to convert viewers into leads. Before launching these ads, you must establish a strong organic presence with a well-crafted LinkedIn page.

Utilizing Sponsored Messaging: Direct and Personal
Sponsored messaging on LinkedIn allows you to send personalized messages to target audience members. These messages can boost conversion rates due to their personal touch. You must use a profile, not a page, to send these messages.
Choose a profile, craft your message, and send it to selected individuals. Sponsored messaging divides into two categories: message ads to redirect to landing pages, and conversation ads to prompt dialogue.

Activity options include cost per click, cost per mile, and cost per send. Cost-per-click charges for each ad click, cost-per-mile charges per 1,000 impressions, and cost-per-send applies to message ads when delivered.
Minimum budget requirements are $10 per day and $10 for total budget ads, offering flexibility in advertising budgets.
